        <p>Generation of diagrams and flowcharts from text in a similar manner as markdown.</p>

        <p>Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?</p>

        <p>This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript.</p>

        <h1>
            <a  class="" href="#syntax" ><span class=""></span></a>Syntax</h1>

        <h2>
            <a class="" href="#graph" ><span class=""></span></a>Graph</h2>

        <p>This statement declares a new graph and the direction of the graph layout.</p>

            <pre><code>graph TD
            </code></pre>

        <p>This declares a graph oriented from top to bottom.</p>

            <pre><code>graph LR
            </code></pre>

        <p>This declares a graph oriented from left to right.</p>

        <p>Possible directions are:</p>

        <ul >
            <li>TB - top bottom</li>
            <li>BT - bottom top</li>
            <li>RL - right left</li>
            <li>LR - left right</li>
            <li>TD - same as TB</li>
        </ul>

        <p>Note that the id is what is displayed in the box.</p>

        <h3>

        <p>It is also possible to set text in the box that differs from the id. If this is done several times, it is the last text
            found for the node that will be used. Also if you define edges for the node later on, you can omit text definitions. The
            one previously defined will be used when rendering the box.</p>

        <h3>
            <a  class="" href="#styling-a-node" ><span class=""></span></a>Styling a node</h3>

        <p>It is possible to apply specific styles such as a thicker border or a different background color to a node.</p>

            <pre><code>graph LR;
                id1(Start)--&gt;id2(Stop);
                style id1 fill:#f9f,stroke:#333,stroke-width:4px;
                style id2 fill:#ccf,stroke:#f66,stroke-width:2px,stroke-dasharray: 5, 5;
            </code></pre>


        <h4>
            <a class="" href="#classes" ><span class=""></span></a>Classes</h4>

        <p>More convenient then defining the style everytime is to define a class of styles and attach this class to the nodes that
            should have a different look.</p>

        <p>a class definition looks like the example below:</p>

            <pre><code>    classDef className fill:#f9f,stroke:#333,stroke-width:4px;
            </code></pre>

        <p>Attachment of a  class to a node is done as per below:</p>

            <pre><code>    class nodeId1 className;
            </code></pre>

        <p>It is also possible to attach a class to a list of nodes in one statement:</p>

            <pre><code>    class nodeId1,nodeId2 className;
            </code></pre>

        <h4>
            <a  class="" href="#default-class" ><span class=""></span></a>Default class</h4>

        <p>If a class is named default it will be assigned to all classes without specific class definitions.</p>

            <pre><code>    classDef default fill:#f9f,stroke:#333,stroke-width:4px;
            </code></pre>

        <h2>
            <a  class="" href="#links-between-nodes" ><span class=""></span></a>Links between nodes</h2>

        <p>Nodes can be connected with links/edges. It is possible to have different types of links or attach a text string to a link.</p>

        <h3>
            <a id="user-content-a-link-with-arrow-head" class="" href="#a-link-with-arrow-head" ><span class=""></span></a>A link with arrow head</h3>

        <h3>
            <a id="user-content-styling-links" class="" href="#styling-links" ><span class=""></span></a>Styling links</h3>

        <p>It is possible to style links for instance a link that is going back in the flow. This is done by the linkStyle statement as in the example below:</p>

            <pre><code>linkStyle 3 stroke:#ff3,stroke-width:4px;
            </code></pre>

        <h2>
            <a id="user-content-interaction" class="" href="#interaction" ><span class=""></span></a>Interaction</h2>

        <p>It is possible to bind a click event to a node:</p>

            <pre><code>click nodeId callback
            </code></pre>

        <ul >
            <li>nodeId is the id of the node</li>
            <li>callback is the name of a javascript function defined on the page displaying the graph, the function will be called with the nodeId as parameter.</li>
        </ul>
